The preceeding chart has been edited so that the height of the tallest column is the same for every county regardless of the actual value. The other columns have been adjusted accordingly to maintain the correct ratio of column heights for each Census. Therefore, this chart should not be used to compare populations between counties.


The chart below has the bars offset to the right to make room for negative values.
